[0024] This disclosure provides a cell reselection method, communication equipment, communication system, storage medium, and program product.

[0025] In a first aspect, embodiments of this disclosure provide a cell reselection method. The method is executed by a terminal. The method includes: determining cell reselection parameters for the terminal based on whether a first condition is met; wherein the terminal includes a main receiver and a low-power receiver.

[0026] In this embodiment, the terminal determines its cell reselection parameters based on whether a first condition is met. Depending on whether the first condition is met or not, the cell reselection parameters can be adjusted differently, ensuring that not all terminals supporting low-power receivers camp on frequencies supporting low-power receivers, thus achieving better load balancing and making the system more stable.

[0027] In conjunction with some embodiments of the first aspect, in some embodiments, the first condition includes at least one of the following: the terminal is not listening to LP-WUS; the terminal is in a medium mobility state or a high mobility state; the terminal is in the cell center or cell edge.

[0028] In this embodiment, the decision to keep a terminal supporting a low-power receiver on a frequency band is determined by three conditions: the terminal is not listening to the Low-Power Wake-up Signal (LP-WUS), the terminal is in a medium or high mobility state, and the terminal is in the cell center or cell edge. Terminals located in the cell center or cell edge have poor communication quality with neighboring cells, and terminals in a medium or high mobility state have difficulty communicating with low-power receivers. This allows the terminal to adjust cell reselection parameters, enhancing the load balancing of the communication system, whether the network instructs the terminal not to listen to LP-WUS due to frequency load imbalance or because the terminal's state does not require low-power receiver-based communication.

[0029] In conjunction with some embodiments of the first aspect, in some embodiments, the cell reselection parameters include at least one of the following: frequency priority; measurement offset.

[0030] In this embodiment, by adjusting frequency priority and / or adding measurement value offsets, it is possible to ensure that not all terminals supporting low-power receivers camp on the low-power receiver's frequency. Thus, different methods can be used to determine cell reselection parameters for different situations, improving the flexibility of cell reselection parameter settings.

[0031] In conjunction with some embodiments of the first aspect, in some embodiments, frequency priority includes at least one of the following: cell reselection priority; cell reselection sub-priority.

[0032] In this embodiment, by using cell reselection priority and cell reselection sub-priority, cell reselection parameters can be adjusted at different granularities, thereby improving the precision of cell reselection parameter adjustment.

[0033] In conjunction with some embodiments of the first aspect, in some embodiments, the operation of determining the cell reselection parameters of the terminal based on whether the first condition is met includes: if the first condition is met, performing at least one of the following: adjusting the frequency priority of the first frequency point from a first level to a second level; determining the frequency priority of the first frequency point as the second level; determining the measurement value offset of the first frequency point, wherein the measurement value offset is less than 0; wherein the first frequency point supports both a master receiver and a low-power receiver, and the first level and the second level are different levels among multiple levels of frequency point priority in cell reselection, with the first level being higher than the second level.

[0034] In this embodiment, when the first condition is met, reducing the frequency priority of the first frequency point supporting the low-power receiver and / or applying a measurement value offset less than 0 to the measurement value of the first frequency point can reduce the chance of the frequency point supporting the low-power receiver being selected, thereby reducing the probability that the terminal supporting the low-power receiver will reside on the frequency point supporting the low-power receiver, avoiding congestion on the frequency point supporting the low-power receiver, and achieving load balancing.

[0035] In conjunction with some embodiments of the first aspect, in some embodiments, the terminal does not listen to LP-WUS, and the second level is the lowest level among multiple levels; or, the terminal is in a medium mobility state or a high mobility state, and / or the terminal is in the cell center or cell edge, and the second level is the level among multiple levels that is only higher than the lowest level.

[0036] In conjunction with some embodiments of the first aspect, in some embodiments, the operation of determining the cell reselection parameters of the terminal based on whether the first condition is met includes: if the first condition is not met, adjusting the frequency priority of the first frequency point from the second level to the first level, wherein the first frequency point supports both the main receiver and the low-power receiver, and the first level and the second level are different levels among multiple levels of frequency point priority in cell reselection, with the first level being higher than the second level.

[0037] In this embodiment, if the first condition is not met, the frequency priority of the first frequency point supporting the low-power receiver is restored from the second level to the first level, which can increase the probability that the first frequency point supporting both the main receiver and the low-power receiver will be selected and remain in service. Thus, when the load on the first frequency point is low, more terminals can be guided back to the first frequency point from other frequencies, achieving dynamic load adjustment.

[0038] In conjunction with some embodiments of the first aspect, in some embodiments, the first level is the highest level among multiple levels, and the second level is the level among multiple levels that is only lower than the highest level.

[0039] In conjunction with some embodiments of the first aspect, in some embodiments, the terminal does not listen to LP-WUS; wherein, the above method further includes: receiving first information sent by a network device, wherein the first information indicates that the terminal does not listen to LP-WUS.

[0040] In this embodiment, the first message sent by the network device can be used to instruct terminals not to listen to LP-WUS. This allows the network device to provide flexible instructions to terminals, avoiding load on frequencies supporting low-power receivers. Specifically, when the load on frequencies supporting low-power receivers is too high, the network device can use the first message to instruct one or more terminals with low-power receivers not to listen to LP-WUS. Thus, by adjusting cell reselection parameters, these terminals can reselect to frequencies that do not support low-power receivers, ensuring that not all terminals supporting low-power receivers camp on those frequencies, achieving load balancing.

[0041] In conjunction with some embodiments of the first aspect, in some embodiments, the first information is carried in one of the following: a non-access stratum (NAS) message; or an access stratum (AS) message.

[0044] In this embodiment, the relationship between the number of cell reselections by the terminal within a first time period and the first threshold, as well as the relationship between the fluctuation of the terminal's measurement value within a second time period and the second threshold, can determine whether the terminal is currently in a medium mobility state or a high mobility state; and then, if the terminal is currently in a medium mobility state or a high mobility state, the cell reselection parameters can be dynamically adjusted.

[0045] In conjunction with some embodiments of the first aspect, in some embodiments, the terminal is located at the center of the cell or the edge of the cell; wherein the measured value of the terminal is less than a third threshold within a third time period; and / or the measured value of the terminal is less than a fourth threshold at a first moment.

In this case, the interfaces in the network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0131] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0132] In some embodiments, the core network equipment may be a single device, multiple devices, or a group of devices. The access network equipment may be virtual or physical. The core network includes, for example, at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next-generation core (NGC).

[0133] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0134] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected.

[0135] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0136] In some embodiments, when the terminal is in an idle or inactive state, continuous cell reselection is required to camp on a higher-priority / better-signal-quality cell. An idle state means the terminal has no ongoing communication connection but remains registered in the system. An inactive state means the terminal has established a connection but is not currently transmitting data.

[0137] In some embodiments, the network can control terminal camping by setting priorities for different frequency points. Simultaneously, the terminal will select the cell with the best signal quality on a given frequency point to provide better service. This achieves mobility management for non-connected terminals.

[0138] In some embodiments, cell reselection can be divided into intra-frequency cell reselection and inter-frequency cell reselection. Intra-frequency cell reselection refers to a terminal reselecting from its current serving cell to another cell within the same frequency band. Intra-frequency cell reselection primarily addresses wireless coverage issues. Inter-frequency cell reselection refers to a terminal reselecting from its current serving cell to another cell in a different frequency band. Inter-frequency cell reselection can be used to address both wireless coverage issues and load balancing.

[0139] In some embodiments, intra-frequency cell reselection can be based on the R criterion, and the specific process is as follows:

[0140] In the first step, the terminal determines whether to start co-frequency measurement by comparing the parameters Srxlev and Squal of the serving cell with the parameters SintrasearchP and SintrasearchQ in the system broadcast: if Srxlev > SintrasearchP and Squal > SintrasearchQ, the terminal can choose not to perform co-frequency measurement; otherwise, the terminal needs to perform co-frequency measurement.

[0141] In some embodiments, Srxlev (cell selection received signal level) is a parameter that measures whether the cell signal strength meets the camping requirements; Squal (cell selection quality value) is a parameter that measures whether the cell signal quality meets the camping requirements. SintrasearchP is a threshold parameter related to signal strength; SintrasearchQ is a threshold parameter related to signal quality (Squal). It should be noted that the calculation methods for Srxlev and Squal are consistent with the calculation methods used during cell selection.

[0142] In the second step, the candidate cells are sorted according to their quality using the R criterion, and the optimal cell is selected.

[0143] In the third step, the optimal cell is determined as a suitable cell based on the suitable cell criterion.

[0144] In some embodiments, cell ranking criteria R are used to evaluate and compare the signal quality of the serving cell and neighboring cells to determine whether cell reselection should be performed.

[0145] In some embodiments, the ranking criterion R of the serving cell s This represents the serving cell's priority or signal quality assessment value, used to determine whether the serving cell is still suitable for the UE to camp on. In one example, R... sDefined as: R s =Q meas,s +Q hyst -Qoffset temp (1).

[0146] In some embodiments, the neighboring cell ranking criterion R n This represents the priority or signal quality assessment value of the neighboring cell, used to determine whether a neighboring cell is superior to the serving cell. In one example, R... n Defined as: R n =Q meas,n -Qoffset-Qoffset temp (2).

[0147] In some embodiments, the definitions of each parameter in formulas (1) and (2) are shown in Table 1 below.

[0148] Table 1

[0149] In some embodiments, during inter-frequency cell reselection, the network can achieve load balancing across different frequency points by setting appropriate priority parameters. The specific process of inter-frequency cell reselection is as follows:

[0150] (a) Measurement

[0151] For frequency points whose priority is higher than the current frequency point as indicated by the system information, the terminal should always perform measurements on them. For frequency points whose priority is equal to or lower than the current frequency point as indicated by the system information, the terminal's measurement criteria are as follows: If the serving cell's Srxlev > SintrasearchP and Squal > SintrasearchQ, the terminal may choose not to perform intra-frequency measurements; if the serving cell's Srxlev > SnonintrasearchP and Squal > SnonintrasearchQ, the terminal may choose not to perform inter-frequency or inter-RAT measurements; otherwise, the terminal needs to perform measurements.

[0152] In some embodiments, SnonintrasearchP is a threshold parameter used to control whether the UE initiates measurements of inter-frequency or inter-system cells when in idle state.

[0153] (b) Priority handling

[0154] The terminal can obtain frequency priority information (common priority) through broadcast messages, or through radio resource control (RRC) release messages (private priority), or inherit it from other RATs when performing inter-RAT cell (re)selection. If a private priority is provided, the terminal will ignore all common priorities. If the system information does not provide priority information for the terminal's currently camped cell, the terminal will set the priority of the frequency point containing that cell to the lowest. The terminal will only perform cell reselection among frequencies that appear in the system information and have provided priorities, according to a priority strategy (preferably selecting frequencies with higher priority).

[0155] In some embodiments, "Inter-RAT cell" refers to the cell relationship between different radio access technologies (RATs). For example, in mobile communications, cell handover or reselection processes between different systems (such as GSM and WCDMA, LTE and NR, etc.) fall under the category of Inter-RAT cells.

[0156] The terminal will remove its dedicated priority if any of the following occurs: the terminal undergoes a state transition; the dedicated priority has expired (exceeding a preset time); or the non-access stratum (NAS) requests PLMN selection.

[0157] In some embodiments, cell reselection criteria may include: cell reselection on high-priority frequencies, cell reselection on frequencies of equal priority, and cell reselection on low-priority frequencies.

[0158] In some embodiments, for cell reselection on a high-priority frequency point, if the terminal has been camped on the current cell for more than 1 second, the process of reselecting the cell to a high-priority frequency point will be performed according to the following criteria: If the system information broadcasts the parameter threshServingLowQ, the high-priority frequency point cell needs to satisfy Squal > Thresh. X,HighQ And the duration exceeds Treselection RAT Only when a cell reselection can be performed; otherwise, high-priority frequency cells need to satisfy Srxlev > Thresh. X,HighP And the duration exceeds Treselection RAT Only then can a neighborhood re-selection be carried out.

[0159] In some embodiments, the parameter threshServingLowQ is used to control the signal quality threshold of the UE when it is on a low-priority frequency or during inter-system cell reselection. X,HighQis used to evaluate the signal quality of high-priority cells. Treselection RAT is a timer parameter, which is used to control the duration for which the terminal continuously evaluates the signal quality or priority condition of a cell when performing cell reselection.

[0160] In some embodiments, for cell reselection on equal priority frequency points, cell reselection on NR frequency points of equal priority shall be performed according to the above-mentioned R criterion based on ranking for intra-frequency cell reselection.

[0161] In some embodiments, for cell reselection on low-priority frequency points, when the camping time of the terminal on the current cell exceeds 1s, the process of cell reselection to a cell on a low-priority frequency point is performed according to the following criteria: if the parameter threshServingLowQ is broadcast in system information, the serving cell needs to satisfy Squal<ThreshServing,LowQ, and the Squal of the cell on the low-priority frequency point is greater than Thresh X,LowP , and this state lasts for more than Treselection RAT , then cell reselection can be performed. Otherwise, the serving cell needs to satisfy Srxlev<ThreshServing,LowP, and the Srxlev of the cell on the low-priority frequency point is greater than Thresh X,LowP , and this state lasts for more than Treselection RAT , then cell reselection can be performed.

[0162] In some embodiments, different moving speeds are determined according to the number of cell reselections that occur within a certain period of time by the terminal. If it is determined that the terminal is in the medium mobility state or high mobility state, it is necessary to scale the parameters Trelection and Q hyst to adapt to the state of the terminal and perform reasonable cell reselection. Relevant parameters for speed determination and scaling criteria are provided by system information.

[0163] In some embodiments, the mobility state detection criteria for a terminal may include: for the normal mobility state criteria, if within the time interval T CRmax the number of cell reselections is less than the medium mobility threshold N CR_M ; for the medium mobility state criteria, if within the time interval T CRmax the number of cell reselections is greater than or equal to N CR_M but less than or equal to the high mobility threshold N CR_H ; for the high mobility state criteria, if within the time interval T CRmaxWithin, the number of cell reselections is greater than N. CR_H .

[0164] In some embodiments, a separate low-power receiver (LR) is introduced to receive power-saving signals. The terminal's modem section or main transceiver section can only be woken up after this separate transceiver is activated; otherwise, the modem section will remain in deep sleep or powered off. The modem section is the core component responsible for wireless communication. The main transceiver section is the UE's radio frequency front-end, responsible for transmitting and receiving wireless signals.

[0165] In some embodiments, not all frequency points in an operator deployment support low-power receivers. Therefore, only some carrier frequencies or frequency bands in the network deployment support low-power receivers. However, it is desirable for all terminals supporting low-power receivers to preferentially camp on the frequency points that support low-power receivers, which would lead to excessive congestion on those frequency points.

[0166] Therefore, how to limit the load on the frequency points that support low-power receivers is a technical problem that urgently needs to be solved.

[0167] Figure 2 is an exemplary flowchart of a cell reselection method provided according to an embodiment of the present disclosure. This disclosure relates to a cell reselection method. As shown in Figure 2, the method includes steps S201 to S204.

[0168] In step S201, network device 102 sends second information to terminal 101.

[0169] In some embodiments, network device 102 may send second information. In some embodiments, the second information may be sent by network device 102, but is not limited thereto, and may also be sent by other entities.

[0170] In some embodiments, terminal 101 may receive second information. In some embodiments, the second information may be received by terminal 101, but is not limited to, and may also be received by other entities.

[0171] In some embodiments, terminal 101 includes a main receiver and a low-power receiver. In some embodiments, terminal 101 may be a communication device having a main receiver and a low-power receiver.

[0172] In some embodiments, the main receiver can be a conventional receiving module of terminal 101 and can be used to receive conventional downlink signals. It is understood that the main receiver can have strong transmission capabilities and achieve high transmission rates; however, the main receiver has high power consumption.

[0173] In some embodiments, a low-power receiver can be used to receive a low-power signal. In some embodiments, the low-power signal can be used to wake up terminal 101. Upon receiving a low-power signal, the main receiver of terminal 101 can be woken up and put into operation. Therefore, the low-power receiver can also be referred to as a low-power wake-up receiver (LP-WUR), and the low-power signal can also be referred to as a low-power wake-up signal (LP-WUS). It is understood that a low-power receiver can have a low transmission rate and low power consumption.

[0174] In some embodiments, the main receiver of terminal 101 may be in a sleep state. In this case, the low-power receiver of terminal 101 may listen for LP-WUS. If terminal 101 detects LP-WUS targeting terminal 101 through the low-power receiver, the main receiver may be woken up.

[0175] In some embodiments, terminal 101 may be in an idle state or an inactive state.

[0203] In some embodiments, the AS message sent by network device 102 to terminal 101 can be used to indicate that the LP-WUS listening of the cell where terminal 101 is located is only used for the release of terminal 101. In other words, under the indication of this AS message, the LP-WUS listening of the cell where terminal 101 is located is not used for the reselection of terminal 101. In some embodiments, the terminal that is locally releasing the cell can perform LP-WUS listening, but the cell is unavailable to the terminal performing the reselection. Therefore, the terminal performing the cell reselection will not select the cell.

[0204] In some embodiments, step S202 may be omitted.

[0205] In step S203, terminal 101 determines whether the first condition is met.

[0206] In some embodiments, terminal 101 may determine the first condition based on second information, and / or protocol agreement, and / or local configuration.

[0207] In some embodiments, upon determining a first condition, terminal 101 may determine whether the first condition is met.

[0208] In some embodiments, the first condition may include terminal 101 not listening to LP-WUS. In some embodiments, terminal 101 may receive first information from network device 102, and the first information may indicate that terminal 101 is not listening to LP-WUS, then terminal 101 may determine that the first condition is met.

[0209] In some embodiments, the first condition may include the terminal 101 being in a medium mobility state or a high mobility state. In some embodiments, the terminal 101 may determine its own mobility state; and if it determines that it is in a medium mobility state or a high mobility state, it determines that the first condition is met.

[0210] In some embodiments, the mobility state of terminal 101 can be determined based on the number of cell reselections performed by terminal 101 within a first time period. It is understood that within the first time period, the greater the number of cell reselections performed by terminal 101, the higher the mobility of terminal 101; conversely, the smaller the number of cell reselections performed by terminal 101, the lower the mobility of terminal 101. In some embodiments, the mobility state of terminal 101 can be determined by comparing the number of cell reselections performed by terminal 101 within the first time period with a threshold. In some embodiments, the number of cell reselections performed by terminal 101 within the first time period may be less than a first threshold, in which case terminal 101 may be in a normal mobility state. In some embodiments, the number of cell reselections performed by terminal 101 within the first time period may be greater than or equal to the first threshold, in which case terminal 101 may be in a medium mobility state or a high mobility state. It is understood that the threshold used to determine the number of cell reselections can be called the cell reselection quantity threshold or the reselection number threshold.

[0211] In some embodiments, the first duration may be configured by the network. For example, network device 102 may send information to terminal 101 to configure the first duration for terminal 101. In some embodiments, the first threshold may be configured by the network. For example, network device 102 may send information to terminal 101 to configure the first threshold for terminal 101. In some embodiments, at least one of the first duration and the first threshold may be carried in higher-layer signaling. For example, the first duration and / or the first threshold may be carried in an RRC message. In some embodiments, at least one of the first duration and the first threshold may be carried in system information. In one example, at least one of the first duration and the first threshold may be carried in an SIB. It is understood that at least one of the first duration and the first threshold may be protocol-defined and / or locally configured, and this disclosure does not specifically limit this aspect.

[0212] In some embodiments, the first duration can be determined by the parameter T. CRmax Indication. In some embodiments, the first threshold may be determined by parameter N. CR_M Instructions. It should be noted that parameter T... CRmax and N CR_M These are parameters broadcast in the system information for the serving cell to determine the terminal's mobility status. Parameter T CRmax Indicates the duration used to assess the allowed number of cell reselections, i.e., the first duration. Parameter N CR_M This indicates the maximum number of cell reselections required to enter the medium mobility state, i.e., the first threshold. For example, in terminal 101 at T... CRmax The number of cell reselections within the first time period indicated is less than parameter N. CR_M Under the indicated first threshold condition, terminal 101 is in a normal mobility state. Parameter T CRmaxand N CR_M This can be applied to speed-based scaling rules. In some embodiments, based on parameter T... CRmax and N CR_M When the mobility status of terminal 101 is determined, a scaling factor can be used to scale the cell reselection time value (e.g., Treselection). This scaling factor can be indicated by system information.

[0213] In some embodiments, the mobility state of terminal 101 can be determined based on the fluctuation of measured values ​​obtained by terminal 101 within a second duration. It is understood that within the second duration, the greater the fluctuation of the measured values ​​obtained by terminal 101 in signal measurement, the higher the mobility of terminal 101; conversely, the smaller the fluctuation of the measured values ​​obtained by terminal 101 in signal measurement, the lower the mobility of terminal 101. In some embodiments, the mobility state of terminal 101 can be determined by comparing the fluctuation of measured values ​​obtained by terminal 101 within the second duration with a threshold. In some embodiments, if the fluctuation of measured values ​​of terminal 101 within the second duration is less than a second threshold, then terminal 101 can be in a normal mobility state. In some embodiments, if the fluctuation of measured values ​​of terminal 101 within the second duration is greater than or equal to the second threshold, then terminal 101 can be in a medium mobility state or a high mobility state. It is understood that the threshold used to judge the fluctuation of measured values ​​can be called the measured value fluctuation threshold or fluctuation threshold.

[0214] In some embodiments, the second duration may be configured by the network. For example, network device 102 may send information to terminal 101 to configure the second duration for terminal 101. In some embodiments, the second threshold may be configured by the network. For example, network device 102 may send information to terminal 101 to configure the second threshold for terminal 101. In some embodiments, at least one of the second duration and the second threshold may be carried in higher-layer signaling. For example, the second duration and / or the second threshold may be carried in an RRC message. In some embodiments, at least one of the second duration and the second threshold may be carried in system information. In one example, at least one of the second duration and the second threshold may be carried in an SIB. It is understood that at least one of the second duration and the second threshold may be protocol-defined and / or locally configured, and this disclosure does not specifically limit this aspect.

[0215] In some embodiments, the second duration and the second threshold may be configuration parameters used to measure the low mobility criterion for evaluating the relaxation criterion.

[0216] In some embodiments, determining the mobility state of terminal 101 based on the number of cell reselections and determining the mobility state of terminal 101 based on the fluctuation of measured values ​​can be implemented selectively or in combination. In one example, if the number of cell reselections by terminal 101 within a first duration is greater than or equal to a first threshold, terminal 101 can be determined to be in a medium mobility state or a high mobility state; otherwise, terminal 101 can be determined to be in a normal mobility state. In one example, if the fluctuation of measured values ​​by terminal 101 within a second duration is greater than or equal to a second threshold, terminal 101 can be determined to be in a medium mobility state or a high mobility state; otherwise, terminal 101 can be determined to be in a normal mobility state. In one example, if the number of cell reselections by terminal 101 within a first duration is greater than or equal to the first threshold, or if the fluctuation of measured values ​​by terminal 101 within a second duration is greater than or equal to the second threshold, terminal 101 can be determined to be in a medium mobility state or a high mobility state; otherwise, terminal 101 can be determined to be in a normal mobility state. In one example, if the number of cell reselections by terminal 101 within a first time period is greater than or equal to a first threshold, and the fluctuation of the measurement value of terminal 101 within a second time period is greater than or equal to a second threshold, terminal 101 can be determined to be in a medium mobility state or a high mobility state; otherwise, terminal 101 can be determined to be in a normal mobility state.

[0217] In some embodiments, the first condition may include the terminal 101 being located at the cell center or cell edge. It is understood that if the signal quality measured by the terminal 101 for a cell is below a threshold, the terminal 101 is considered to be at the cell center or cell edge. This cell may be a neighboring cell of the cell where the terminal 101 is camped. In some embodiments, the terminal 101 may determine its location in a neighboring cell based on the measured signal quality.

[0218] In some embodiments, the location of terminal 101 in neighboring cells can be determined based on the measurement values ​​of terminal 101 relative to neighboring cells within a third time period. In some embodiments, if the measurement values ​​of terminal 101 relative to neighboring cells within the third time period are less than a third threshold, it can be determined that terminal 101 is located at the cell center or cell edge. In some embodiments, if the measurement values ​​of terminal 101 relative to neighboring cells within the third time period are greater than or equal to the third threshold, it can be determined that terminal 101 is not located at the cell center or cell edge.

[0219] In some embodiments, the third duration may be configured by the network. For example, network device 102 may send information to terminal 101 to configure the third duration for terminal 101. In some embodiments, the third threshold may be configured by the network. For example, network device 102 may send information to terminal 101 to configure the third threshold for terminal 101. In some embodiments, at least one of the third duration and the third threshold may be carried in higher-layer signaling. For example, the third duration and / or the third threshold may be carried in an RRC message. In some embodiments, at least one of the third duration and the third threshold may be carried in system information. In one example, at least one of the third duration and the third threshold may be carried in an SIB. It is understood that at least one of the third duration and the third threshold may be protocol-defined and / or locally configured, and this disclosure does not specifically limit this aspect.

[0220] In some embodiments, the location of terminal 101 in neighboring cells can be determined based on the measurement value of terminal 101 relative to the neighboring cells. In some embodiments, if the measurement value of terminal 101 relative to the neighboring cells is less than a fourth threshold, it can be determined that terminal 101 is located at the cell center or cell edge. In some embodiments, if the measurement value of terminal 101 relative to the neighboring cells is greater than or equal to the fourth threshold, it can be determined that terminal 101 is not located at the cell center or cell edge.

[0221] In some embodiments, the fourth threshold may be configured by the network. For example, network device 102 may send information to terminal 101 to configure the fourth threshold for terminal 101. In some embodiments, the fourth threshold may be carried in higher-layer signaling. For example, the fourth threshold may be carried in an RRC message. In some embodiments, the fourth threshold may be carried in system information. In one example, at least one of the fourth thresholds may be carried in the SIB. It is understood that the fourth threshold may be protocol-defined and / or locally configured, and this disclosure does not specifically limit this aspect.

[0222] In some embodiments, the third threshold and the fourth threshold may be the same or different, and this disclosure does not specifically limit this.

[0223] In some embodiments, one or more of the third duration, the third threshold, and the fourth threshold may be configuration parameters used to evaluate the signal quality good criterion for assessing the measurement relaxation criterion.

[0224] In some embodiments, the measurements of neighboring cells may include at least one of the following: the signal strength of the neighboring cell and the signal quality of the neighboring cell. In some embodiments, the signal strength of the neighboring cell may include the reference signal received power (RSRP). In some embodiments, the signal quality of the neighboring cell may include at least one of the following: RSRQ and signal-to-interference-plus-noise ratio (SINR).

[0225] In some embodiments, the three conditions in the first condition—that terminal 101 does not listen to the Low Power Wake-up Signal (LP-WUS), terminal 101 is in a medium mobility state or a high mobility state, and terminal 101 is in the cell center or cell edge—can be used independently to determine whether the first condition is met. In one example, terminal 101 does not listen to LP-WUS, so the first condition is met. In another example, terminal 101 is currently in a medium mobility state or a high mobility state, so the first condition is met. In yet another example, terminal 101 is currently in the cell center or cell edge, so the first condition is met.

[0226] In some embodiments, the three conditions in the first condition—that terminal 101 does not listen to the Low Power Wake-up Signal (LP-WUS), terminal 101 is in a medium mobility state or a high mobility state, and terminal 101 is in the cell center or cell edge—can be combined to determine whether the first condition is met. In one example, if terminal 101 does not listen to LP-WUS and is currently in a medium mobility state or a high mobility state, then the first condition is met. In another example, if terminal 101 is currently in a medium mobility state or a high mobility state and is currently in the cell center or cell edge, then the first condition is met. In yet another example, if terminal 101 is currently in the cell center or cell edge and does not listen to LP-WUS, then the first condition is met.

[0227] In step S204, terminal 101 determines the cell reselection parameters.

[0228] In some embodiments, terminal 101 can determine cell reselection parameters based on whether a first condition is met.

[0229] In some embodiments, cell reselection parameters may include at least one of the following: frequency priority; measurement offset.

[0230] In some embodiments, frequency priority can be used to implement cell reselection. In some embodiments, frequency priority can be used to determine the priority relationship between one or more frequencies during the cell reselection process.

[0231] In some embodiments, frequency priority can have multiple levels. For example, frequency priority can have 5 levels, 7 levels, or other numbers of levels. For example, in the case of 7 levels, 7 is the highest level and 1 is the lowest level. For example, in the case of 5 levels, 5 is the highest level and 1 is the lowest level.

[0232] In some embodiments, frequency priority may also be referred to as frequency priority, reselection priority, etc., and the names are not limited in the embodiments disclosed herein.

[0233] In some embodiments, the cell where terminal 101 is currently camped may be referred to as the serving cell, and one or more neighboring cells may exist around the serving cell. In some embodiments, the frequency of the serving cell and the frequency of at least one neighboring cell may be the same. In this case, the serving cell and the neighboring cell with the same frequency may have the same priority. In some embodiments, the frequency of the serving cell and the frequency of at least one neighboring cell may be different. In this case, the frequency of the neighboring cell may have a higher priority, the same priority, or a lower priority relative to the frequency of the serving cell; correspondingly, the neighboring cell may have a higher priority, the same priority, or a lower priority relative to the serving cell.

[0234] In some embodiments, frequency priority may include at least one of the following: cell reselection priority and cell reselection sub-priority. In some embodiments, cell reselection priority may be an absolute priority for a specific carrier frequency during the cell reselection process. In some embodiments, cell reselection priority may be an integer. For example, the value of cell reselection priority may be 0, 1, or 2. In some embodiments, cell reselection sub-priority may be an absolute priority for a specific carrier frequency during the cell reselection process. In some embodiments, cell reselection sub-priority may be a fraction. For example, the value of cell reselection sub-priority may be 0.2, 0.4, 0.6, or 0.8. It is understood that the frequency priority of a frequency point may consist of cell reselection priority and cell reselection sub-priority. For example, the value of frequency priority may be equal to 1.2, 2.8, or other values. Of course, frequency priority may also apply only to cell reselection priority.

[0235] In some embodiments, the cell reselection priority for a frequency point can be configured by the parameter CellReselectionPriority.

[0236] In some embodiments, the cell reselection subpriority for a frequency point can be configured by the parameter CellReselectionSubPriority.

[0237] In some embodiments, the measurement offset can be used to adjust the measurement value of the measurement signal obtained by the terminal 101.

[0238] In some embodiments, the measurement offset can be greater than 0. For example, the measurement offset can be equal to 0.2 dBm. In some embodiments, the measurement offset can be less than 0. For example, the measurement offset can be equal to -0.2 dBm. In some embodiments, the magnitude of the measurement offset can be agreed upon by the protocol or configured by the network. It is understood that if the measurement offset of a cell is less than 0, the adjusted measurement value is lower, and the probability of that cell being selected is lower, or that cell is not selected as a candidate cell for cell reselection. Conversely, if the measurement offset of a cell is greater than 0, the adjusted measurement value is higher, and the probability of that cell being selected is higher, or that cell is directly selected as a candidate cell for cell reselection.

[0239] In some embodiments, the magnitude of the measurement value offset may be the same or different for different first conditions. In some embodiments, the measurement value offsets corresponding to the three conditions—terminal 101 not listening to LP-WUS, terminal 101 being in a medium mobility state or a high mobility state, and terminal 101 being in the cell center or cell edge—may be the same. In some embodiments, the measurement value offsets corresponding to at least two of the three conditions—terminal 101 not listening to LP-WUS, terminal 101 being in a medium mobility state or a high mobility state, and terminal 101 being in the cell center or cell edge—may be different. For example, the measurement value offset when terminal 101 is not listening to LP-WUS may be different from the measurement value offset when terminal 101 is in a medium mobility state or a high mobility state. For example, the measurement value offset when terminal 101 is in a medium mobility state may be different from the measurement value offset when terminal 101 is in a high mobility state. For example, the measurement value offset when terminal 101 is in a medium mobility state may be different from the measurement value offset when terminal 101 is in a high mobility state. For example, the measurement offset when terminal 101 is at the center of the cell can be different from the measurement offset when terminal 101 is at the edge of the cell.

[0240] In some embodiments, step S204 may include at least one of the following: adjusting frequency point priority; adding measurement value offset. In some embodiments, if the first condition is met, terminal 101 may adjust the frequency point priority and / or add a measurement value offset to the measurement value. By adjusting the frequency point priority and / or adding a measurement value offset, the probability of terminal 101 selecting a frequency point that supports low-power receivers during cell reselection can be reduced, avoiding congestion of frequency points that support low-power receivers.

[0241] In some embodiments, the frequency points deployed in the serving cell and neighboring cells may include a first frequency point and a second frequency point. The first frequency point supports both the main receiver and the low-power receiver of terminal 101. In other words, both the main receiver and the low-power receiver of terminal 101 can operate on the first frequency point. The second frequency point only supports the main receiver. In other words, the low-power receiver cannot operate on the second frequency point.

[0242] In some embodiments, the number of first frequency points can be one or more. In some embodiments, the number of second frequency points can be one or more.

[0243] In some embodiments, one or more first frequency points and / or first or more second frequency points may be deployed in a cell.

[0244] In some embodiments, the operation of determining the cell reselection parameters of terminal 101 may include at least one of the following: adjusting the frequency priority of the first frequency point from the first level to the second level; determining the priority of the first frequency point as the second level; and determining the measurement value offset of the first frequency point.

[0245] In some embodiments, terminal 101 can adjust the frequency priority of the first frequency point from a first level to a second level. In one example, terminal 101 can adjust the frequency priority of the first frequency point of the serving cell from a first level to a second level. In another example, terminal 101 can adjust the frequency priority of the first frequency point of a neighboring cell from a first level to a second level. In some embodiments, the second level is lower than the first level. In this case, terminal 101 can reduce the priority of the first frequency point in cell reselection.

[0246] In some embodiments, the first level can be any level other than the lowest level among multiple levels. For example, if the frequency priority for cell reselection can be divided into 7 levels, then the first level can be any level from level 7 to level 2.

[0247] In some embodiments, the second level can be any level other than the highest level among multiple levels. For example, if the frequency priority for cell reselection can be divided into 7 levels, then the first level can be any level from level 6 to level 1.

[0248] In some embodiments, the first level is higher than the second level. In one example, the frequency priority in cell reselection is divided into 7 levels. For example, the first level can be level 7, and the second level can be any of level 6 to level 1. For example, the first level can be level 6, and the second level can be any of level 5 to level 1. The first level can be level 2, and the second level can be level 1.

[0249] In some embodiments, the terminal 101 can reduce the frequency priority of the first frequency point by adjusting the frequency priority of the first frequency point from the first level to the second level.

[0250] In some embodiments, terminal 101 may first determine the reduction magnitude of the frequency priority of the first frequency point, and then determine the second level based on the current first level and the reduction magnitude. In some embodiments, terminal 101 may determine the reduction magnitude to be one level, that is, reducing the frequency priority of the first frequency point by one level. In this case, terminal 101 may reduce the frequency priority of the first frequency point from the current first level by one level to reach the second level. In one example, the first level is the highest level among multiple levels, then when the reduction magnitude is one level, terminal 101 may reduce the frequency priority of the first frequency point from the highest level to the second highest level, that is, only lower than the highest level. For example, terminal 101 may reduce the frequency priority of the first frequency point from the highest level 7 to level 6 by one level. In some embodiments, terminal 101 may determine the reduction magnitude to be two levels, that is, reducing the frequency priority of the first frequency point by two levels. In this case, terminal 101 may reduce the frequency priority of the first frequency point from the current first level by two levels to reach the second level. For example, the first level is the highest level among multiple levels, then when the reduction magnitude is two levels, terminal 101 may reduce the frequency priority of the first frequency point from the highest level to the third highest level. For example, terminal 101 can reduce the frequency priority of the first frequency point from the highest level 7 to level 5 by two levels.

[0251] In some embodiments, terminal 101 may first determine a second level of frequency priority for the first frequency point, and then adjust the frequency priority from the first level to the second level. In some embodiments, terminal 101 may determine the adjusted second level. It is understood that in this case, terminal 101 may not know the reduction amount, but directly obtain the second level. For example, terminal 101 may reduce the frequency priority of the first frequency point from the highest level 7 to level 6. For example, terminal 101 may reduce the frequency priority of the first frequency point from the highest level 7 to level 5.

[0252] In some embodiments, terminal 101 can set the frequency priority of the first frequency point to a second level. In one example, terminal 101 can directly set the frequency priority of the first frequency point of the serving cell to the second level. In another example, terminal 101 can directly set the frequency priority of the first frequency point of a neighboring cell to the second level. In this case, terminal 101 can set the first frequency point to have a lower level in cell reselection.

[0253] In some embodiments, the second level can be any level other than the highest level among multiple levels. For example, in the case where the frequency priority for cell reselection is divided into 7 levels, the second level can be any level from level 6 to level 1.

[0254] In some embodiments, terminal 101 can directly set the frequency priority of the first frequency point to the second level without considering the first level. In one example, terminal 101 can set the frequency priority of the first frequency point to level 3. It should be noted that in this case, the second level can be a lower level among multiple levels. For example, if the frequency priority includes 7 levels, the second level can be level 1, level 2, or level 3.

[0255] In some embodiments, the first level can be the highest level in frequency priority. In some embodiments, the second level can be the second highest level in frequency priority, i.e., only lower than the highest level. In one example, frequency priority can include 5 levels, numbered 1, 2, 3, 4, and 5 from lowest to highest. The first level can be 5, and the second level can be 4.

[0256] In some embodiments, the first level and / or the second level may be protocol-defined and / or locally configured. In some embodiments, terminal 101 may determine the first level and / or the second level according to protocol-defined and / or locally configured. In some embodiments, the first level and / or the second level may be network-configured. In some embodiments, terminal 101 may receive configuration information from network device 102, which is used to configure the first level and / or the second level. In some embodiments, the configuration information for configuring the first level and / or the second level may be carried in dedicated signaling or broadcast signaling. In one example, network device 102 may send the first level and / or the second level of a first frequency point via broadcast signaling such as SIB. In one example, network device 102 may send the first level and / or the second level of a first frequency point via dedicated signaling such as an RRC release message.

[0257] In some embodiments, the adjustment from the first level to the second level may include an adjustment of cell reselection priority and / or cell reselection sub-priority. In some embodiments, each of the first and second levels may include both cell reselection priority and cell reselection sub-priority. For example, the first level may be 1.4 and the second level may be 1.2. For example, the first level may be 2.8 and the second level may be 1.2. In some embodiments, each of the first and second levels may include only cell reselection priority. For example, the first level may be 5 and the second level may be 4.

[0258] In some embodiments, terminal 101 may add a measurement value offset to the measurement value of the first frequency point. In some embodiments, the measurement value offset of the first frequency point may be a negative offset, that is, the measurement value offset is less than 0.

[0259] In some embodiments, network device 102 can instruct terminal 101 not to listen to LP-WUS via NAS or AS messages. In this case, terminal 101 can adjust the frequency priority of the first frequency point from a first level to a second level, or set the frequency priority of the first frequency point to the second level, or add a measurement offset to the measurement value of the first frequency point. In one example, the first level can be the highest level, the second highest level, or another level. In one example, the second level can be the lowest level, the second lowest level, or another level.

[0260] In some embodiments, terminal 101 may be in a medium mobility state or a high mobility state, and / or in the cell center or cell edge. In this case, terminal 101 may adjust the frequency priority of the first frequency point from a first level to a second level, or set the frequency priority of the first frequency point to the second level, or add a measurement value offset to the measurement value of the first frequency point. In one example, the first level may be the highest level, the second highest level, or another level. In one example, the second level may be the lowest level, the second lowest level, or another level.

[0261] In some embodiments, frequency priority is adjusted during frequency point measurement and / or measurement value sorting in cell reselection of terminal 101. In some embodiments, adjustment of frequency priority can be used for frequency point measurement and / or measurement value sorting in cell reselection of terminal 101.

[0262] In some embodiments, during cell reselection, terminal 101 can determine the priority of each frequency point. In some embodiments, during frequency point measurement, the measurement of multiple frequency points can be performed according to the determined frequency point priority. For example, terminal 101 can first perform frequency point measurement on the frequency point with the highest priority, i.e., perform cell reselection for the highest-level frequency point; then, terminal 101 can perform frequency point measurement on the next highest-level frequency point, i.e., perform cell reselection for the next highest-level frequency point; and so on. If a first condition is met, terminal 101 can adjust the frequency point priority of the first frequency point during the above frequency point measurement process.

[0263] In some embodiments, during the measurement value sorting process, terminal 101 can sort the measurement values ​​of cells corresponding to multiple frequency points. During the sorting process, the measurement values ​​of cells corresponding to frequency points with higher priority may precede the measurement values ​​of cells corresponding to frequency points with lower priority. If a first condition is met, terminal 101 can adjust the frequency point priority of the first frequency point during the measurement value sorting process.

[0264] In some embodiments, the measurement value offset is added during the measurement value sorting in cell reselection of terminal 101. In some embodiments, the measurement value offset is used to adjust the measurement values ​​during the measurement value sorting in cell reselection of terminal 101. In some embodiments, during the measurement value sorting process, terminal 101 can add a measurement value offset to the measurement values ​​of the cell corresponding to the first frequency point. For example, terminal 101 can add a negative measurement value offset to the measurement values ​​of the cell corresponding to the first frequency point, causing the measurement value to decrease.

[0265] In some embodiments, when terminal 101 is not listening to LP-WUS, terminal 101 can set the frequency priority of the first frequency point to the lowest level during frequency point measurement. It is understood that when terminal 101 is in the cell center of the serving cell and terminal 101 is currently on the first frequency point, by setting the frequency priority of the first frequency point to the lowest level, terminal 101 does not need to measure the serving cell.

[0266] In some embodiments, when terminal 101 is not listening to LP-WUS, terminal 101 may set the frequency priority of the first frequency point to the lowest level during the measurement value sorting process.

[0267] In some embodiments, step S204 may include: if the first condition is not met, terminal 101 adjusts the frequency priority of the first frequency point from the second level to the first level. In some embodiments, if the first condition is met, terminal 101 may adjust the frequency priority of the first frequency point from the first level to the second level. Then, if the first condition is no longer met, terminal 101 may readjust the frequency priority of the first frequency point from the second level back to the first level. In this way, the frequency priority of the first frequency point is restored to the first level.

[0268] The cell reselection method of this embodiment can be realized through the above steps S201 to S204.

[0310] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0311] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0312] In some embodiments, terminals supporting a specific type (LR) are limited to adjusting cell reselection parameters when a condition (i.e., a first condition) is met.

[0313] In some embodiments, adjusting cell reselection parameters may involve adjusting cell reselection parameters for a specific frequency (i.e., a frequency that supports LR, corresponding to the first frequency point mentioned above).

[0314] In some embodiments, cell reselection parameters may include priority (i.e., frequency priority), where priority may refer to cell reselection priority.

[0315] In some embodiments, adjusting cell reselection parameters can involve adjusting the measured values. For example, an offset (i.e., a measurement offset) can be added to the signal quality of the measured cell (which may be the serving cell or a neighboring cell) at that frequency.

[0316] In some embodiments, the offset can be either positive or negative. If a negative offset is applied, the adjusted measurement value is lower, meaning the cell has a lower probability of being selected or is not selected as a reselection candidate. This allows for flexible adjustment of the probabilities of the serving cell and neighboring cells in cell reselection.

[0317] In some embodiments, a particular type of terminal is a terminal with specific hardware functions, such as a terminal with LR.

[0318] In some embodiments, the priority of a specific frequency for cell reselection can be adjusted by: adjusting the priority of the specific frequency or band from the first level to the second level when the conditions are met; or, directly using the second level for cell reselection for the specific frequency.

[0319] In some embodiments, the first level can be a protocol agreement or network configuration; wherein, the network configuration method can be dedicated signaling or broadcast signaling. For example, the network can be configured to set the frequency or frequency band supporting LR to a specific priority level, such as the highest priority level, for terminals that support LR.

[0320] In some embodiments, the first priority level can be the highest priority level.

[0321] In some embodiments, the second level may be a protocol agreement or a network configuration; wherein, the network configuration method may be dedicated signaling or broadcast signaling.

[0322] In some embodiments, the second priority level may be the second highest priority level.

[0323] In some embodiments, the system can revert from the second level to the first level if the conditions are not met.

[0324] In some embodiments, the above priority levels may apply to CellReselectionPriority (i.e., cell reselection priority) and / or sub-priority CellReselectionSubPriority (i.e., cell reselection sub-priority).

[0325] In some embodiments, if it applies to CellReselectionPriority, only CellReselectionPriority is adjusted, and the sub-priority remains unchanged; if it applies to SubPriorityCellReselectionSubPriority, only SubPriorityCellReselectionSubPriority is adjusted, and the cell reselection priority remains unchanged.

[0326] In some embodiments, the fulfillment of a specific condition may include: whether a certain business feature is indicated by a higher level as to whether it is available.

[0327] In some embodiments, the NAS can indicate whether the terminal can currently use LP-WUS to listen for wake-up signals.

[0328] In some embodiments, the granularity of the NAS indicating the terminal can be the indication granularity per UE or the granularity per paging group.

[0329] In some embodiments, NAS signaling messages can be used to indicate whether the terminal can currently use LP-WUS to listen for wake-up signals; for example, during the attach interaction process, NAS signaling messages can be used to indicate whether the terminal can currently use LP-WUS to listen for wake-up signals.

[0330] In some embodiments, the NAS can instruct the terminal that it cannot currently use LP-WUS to listen for wake-up signals. Even terminals supporting LP-WUS will not consider LR-supported frequency bands as high priority. Thus, under certain conditions, the terminal will not preferentially choose LR-supported frequency bands, thereby alleviating congestion problems on the LR band.

[0331] In some embodiments, the fulfillment of a specific condition may include whether a certain service feature is indicated by the AS as available.

[0332] In some embodiments, the AS can indicate whether the terminal can currently use LP-WUS to listen for wake-up signals.

[0333] In some embodiments, the AS may instruct the terminal to limit LP-WUS listening to the cell to the locally released terminal only, meaning that it will not be available to the reselected terminal.

[0334] In some embodiments, the AS can indicate through system messages whether the terminal can currently use LP-WUS to listen for wake-up signals.

[0335] In some embodiments, during cell reselection, a terminal supporting LP-WUS prioritizes LP-WUS-enabled cells that allow the user reselected from the previous cell to use the cell. If a neighboring cell does not support the user reselected from the previous cell, it can either not be selected as a reselection candidate cell or have a negative offset added to its measurement signal, thus reducing the probability of that cell being selected. Therefore, under certain conditions, the terminal will not be preferentially selected for a particular cell, which will alleviate congestion on that cell. In some embodiments, these specific conditions may include: the terminal is currently in a medium mobility state or a high mobility state.

[0336] In some embodiments, the mobility state of the terminal may be determined based on one or more of the following methods.

[0337] In some embodiments, the mobility status of a terminal can be determined based on the number of cell reselections that occur within a specific time period. The specific time period and the number of reselections can be network configurations; or existing configuration parameters used for scaling rules can be reused.

[0338] In some embodiments, the mobility status of a terminal can be determined based on whether the fluctuation of the signal measured within a specific time period is less than a threshold: wherein the specific time period and the fluctuation threshold can be network configuration; or the configuration parameters used by the low mobility criteria for measuring relaxation criteria assessment broadcast in the original SIB can be reused.

[0339] In some embodiments, for highly mobile terminals, frequency bands (i.e., frequency points) that support LR will not be considered as high priority.

[0340] In some embodiments, the specific conditions may include: the terminal is currently in the center or edge of the serving cell, or the terminal is currently in the center or edge of a neighboring cell.

[0341] In some embodiments, the location of the terminal—whether it is at the center of the serving cell or a neighboring cell, or at the cell edge—is determined based on whether the signal strength detected within a specific time period is higher than a threshold. The specific time period and threshold can be configured by the network; or the configuration parameters used for the signal quality good criterion evaluation in the original SIB broadcast for the relaxation criterion evaluation of the cell assessment measurement can be reused.

[0342] In some embodiments, the terminal is determined to be at the center of the serving cell or a neighboring cell or at the cell edge based on whether the signal strength detected within a specific time period is higher than a threshold.

[0343] For terminals located at the cell edge, since their probability of using LR (Local Reselection) is reduced, it's advisable to add a negative offset to the cell's measurement value during reselection, or to lower the cell's reselection priority. This will prevent the terminal from being preferentially selected for that cell, thus alleviating congestion issues on that cell.

[0344] In some embodiments, the location of the terminal, whether in the center or edge of a neighboring cell, is determined based on whether the currently detected signal strength is higher than a threshold. The specific time period and threshold can be configured by the network; or the configuration parameters used in the original SIB for evaluating the good signal quality criterion for the relaxation criteria of the cell assessment measurement can be reused.

[0345] In some embodiments, for example: if the terminal is currently in cell A, and a neighbor cell measurement is triggered, and the signal quality of neighbor cell B (MR+LR) is measured to be below a threshold, then to reduce the chance of that neighbor cell being selected, the measurement value of the neighbor cell can be reduced by an offset value. (Because according to the existing mechanism, if the MR+LR frequency point has the highest priority, higher than another frequency point that only supports MR, even if the signal quality is lower than a cell with a lower frequency point, it will still be selected first. However, in reality, even if the terminal selects this frequency band, it cannot use LP-WUS.)

[0346] In some embodiments, the above conditions may be combined or determined separately.

[0347] Therefore, by taking into account additional conditions (such as whether the first condition is met) during cell reselection, the reselection probability of a user reselecting to a certain frequency / band or cell can be flexibly adjusted, thus enabling flexible load adjustment.

[0348] In some embodiments, terminals that support LR, but are instructed by higher layers or the AS layer not to use LP-WUS monitoring, will set the LR-supported frequency bands to the lowest priority level.

[0349] In some embodiments, terminals that support LR, but are currently in low mobility or at the cell edge, will set the frequency bands supporting LR to the second lowest priority.

[0350] In some embodiments, adjusting the priority of a specific frequency for cell reselection can be applied to determining the frequency priority during the cell reselection process. That is, the frequency band or frequency can be flexibly adjusted during the measurement process; for example, low-priority frequency bands or frequencies do not need to be measured, reducing power consumption during the measurement process.

[0351] In some embodiments, terminals that support LR, but are instructed by higher layers or the AS layer not to use LP-WUS monitoring, will set the frequency band that supports LR to the lowest priority level; in this case, it is not necessary to measure the frequency band that supports LR, thus reducing power consumption during the measurement process.

[0352] In some embodiments, adjusting the priority / adding offset for a specific frequency used for cell reselection can be applied to the priority determination when ranking is performed after measurement is completed during the cell reselection process.

[0353] In some embodiments, terminals that support LR, but for which higher layers or the AS layer instructs terminals that do not use LP-WUS monitoring to set the frequency band supporting LR to the lowest priority level, will be set to the lowest priority level during sorting.

[0354] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc.
